Answer:50%
Step-by-step explanation:
Neighborhood A: 30 homes and increases by 20% per year
Neighborhood B: 45 homes and increases by 3 per year.
N.A = 30 (1.20)^t
N.B = 45 + 3(t)
t = 5
N.A = 30(1.20)^5 = 30(2.48832) = 74.65 or 75
<span>N.B = 45 + 3(5) = 45 + 15 = 60</span>
Answer:
D
Step-by-step explanation:
In order to get from meters to centimeters, you multiply by 100. Therefore, you do 12 x 100 which equals 1200. From there you multiply 1200 x 2 and add that onto 400 x 2. (or 1200+1200+400+400)
By multiplying fractions, you aren't changing any of them. For example 1/2 times 1/3 all you do is multiply. But to add 1/2 and 1/3 you would have to get a common denominator.<span />
